阿摩線上測驗
51.下列強心苷，何者不含葡萄糖基？
(A)digitoxin
(B)purpurea glycoside A
(C)lanatoside A
(D)scillaren A
統計： A(4704), B(474), C(633), D(2858), E(0) #1528102
詳解 (共 10 筆)
強心配醣體顧名思義水解後幾乎都有醣類成分 通常為Glucose , Rhamnose 等等
每一種生藥的主成分&水解後的醣類 ,都常出現於國考題中
毛地黃(A)Digitoxin >>>3 digitoxose
毛地黃(B)Purpurea glycoside A >>>3 digitoxose+1 Glucose
長葉毛地黃(C)Lanatoside A >>>3digitoxose+1 Glucose+1acetyl
海蔥(D)Scillaren A>>>Scillarenin+Rhamnose+Glucose

補充
Ouabain(G-strophanthoside): Ouabagenin+Rhamnose
Stroposide(K-strophanthoside):Strophanthidin+Cymarose+α-Glucose+β-Glucose
Convallatoxin:Strophanthidin+Rhamnose
記憶: O跟G 相似 / K配S Kill Steal 尾刀/撿尾
發現只要是有個大寫字母在後面的(ABCDE等等)都有glucose
(不只這些 只列出常出題的)
| 基原 | 毛地黃 Digitalis purpurea | 長葉毛地黃 Digitalis lanta |
| 別稱 | 洋地黃Foxglove | 狹葉毛地黃Grecian foxglove |
| 成分 | Purpurea glycoside A --- Digitoxin Purpurea glycoside B --- Gitoxin ... | Lanatoside A --- Digitoxin Lanatoside B --- Gitoxin Lanatoside C --- Digoxin Lanatoside D Lanatoside E |
57 強心苷 lanatoside C 結構上所接的糖基為：
(A) 3 Digitoxose＋1 glucose
(B) 2 Digitoxose＋1 acetyldigitoxose＋1 glucose
(C) 3 Digitoxose
(D) 2 Digitoxose＋1 acetyldigitoxose
ABCDE的都是四糖苷(1葡萄糖+3毛地黃毒糖)
--xin都是三糖甘(3毛地黃毒糖)
